Troubleshooting
The overload relay blows
The supply voltage of the machine is too low.
A gaping contact in the power feed from the switchboard to the motor: check the voltage drop in the
junctions.
The relay has been wrongly installed. The relay value should be 35 – 40 A.
An insufficient contact in the phase conductor: check the power line for damages and the fastening of the
cables to the contact.
Too high a voltage drop, short power source, or too short a power line.
Too much power off take, due to dirt or a leakage in the hydraulic system: check the drain valve.
Check that the voltage between the phases is the same. The motor may have been damaged.
Alarms
Alarms are indicated with a signal sound, which lasts for one second when a new alarm is activated.
An error message/code is shown in the Service display, until the fault that has caused the alarm has
disappeared.
An alarm is also indicated with indicator lights in the remote control.
Indicator lights
The
PowerOn
indicator light connected to the frame module, functions as ”a rear light” of the machine. It
is also used to indicate the working condition of the control system. If the control system is functional and
controls are allowed, the indicator light is lit continuously.
If there is a fault in the control system, that prevents the safe control of all movements, the light flashes
on and off. The light also flashes if the emergency stop circuit has not been acknowledged, by pressing the
acknowledgement button
(Ack)
after turning on the remote control or if the ”dead man function” prevents
the control of movements.
If no operating voltage is connected to the control system or if the emergency stop circuit has been cut, the
indicator light is not lit at all.
The other indicator lights of the system are in the remote control (see also Structure section)!
The
System
indicator light is green, when the control system is in order. It blinks red, when a new alarm is
activated and continues blinking until the alarm has been acknowledged with the acknowledgement button
(Ack)
of the remote control. After the acknowledgement, the indicator light is red until the fault has been
corrected. The indicator light expresses all the general faults in the channel, valve control, etc. of the control
system.
The
Oil Temp
indicator light is green, when the temperature of the hydraulic oil is within the approved
limits. It blinks red after a temperature alarm is activated and continues blinking until the alarm has
been acknowledged with the acknowledgement button
(Ack)
of the remote control. After the
acknowledgement, the indicator light is red until the fault has been corrected.
